Chris will have to speak to that, but in general one would adjust this if
(s)he thought the metering consistently erred compared to his/her artistic
vision. This is essentially the same as using a fake EI (say, EI 200 for
Tri-X) to trick a film camera into giving you an exposure other than what
it thinks is right.

Note that you can adjust flash exposure compensation, as well. I have that
set to -2/3 stop, so I can flip the flash on for some fill and get what I
think is a natural amount (auto flashes always give a bit too much fill,
IMO, and the pics look unnatural).

Someone suggested using bracketed images to get a longer exposure scale,
and you replied that people photos don't stand around and wait for the next
exposure. The G5 will auto-bracket (FUNC, then down two icons). I just
tried it, and the exposures are made a bit less than a second apart
according to my calibrated ear (!). This may still be too slow, but much
faster than taking another shot manually. (DSLRs do this quicker -- my 10D
takes a 3-shot bracketed series in less than a second, shutter speed
permitting.) Alternatively, the G5 will focus bracket, if you want.

Best reegards,
